Why can't you power the Pi's from the Vectrex 5V? Pi0W crashes near the end of the boot sequence just before starting the program. Presumably due to insufficient current. And Thomas was a bit worried that the 5V track on the Vecfever from which I was tapping off the power was too thin for the amount of power it would have pulled if it were working properly. Another possibility is that the Vectrex's supply isn't well enough regulated and the voltage was being pulled too low, and that was what caused the Pi to reset. I haven't yet put a meter in the circuit to measure the current and voltage properly - I guess I could do but for now I'm putting that aspect of the project aside and and getting on with the remaining software issues.

PS Note that since the Pi Zero W has built-in Wireless (and Bluetooth), this will also mean that those of you who wanted a networked Vectrex should finally be able to have one! So then, how about a two, or more, player Tailgunner that takes advantage of the wireless capability in order to link the Vectrex Pi Zero carts? This version could be one where the opposing player(s) takes on the role(s) of one of the attacking ships? The opposing player's view could show the Tailgunner's aim so it could attempt to be avoided. Also, the opposing player could have a shield to block incoming fire one or two times during their run at the Tailgunner's ship. For two-player only game maybe even make it 3D/4D space where the two players battle. 360 view. But the farthest distance the two player' ships are separated is limited in order to prevent player two from being outside of tailgunner range.

4D space?

I got a rpi zero and a rpi zero w today, waiting for something to happen now I already added a header so I can use TV as a monitor

Remember I'm hacking a decompilation of the rom back into very low-level C... very few of these suggestions are in scope - I can kill a few suboutine calls and I can insert some high-level C in places but more or less the format of the game is fixed. What I can do possibly is add a global high score with name or initial entry at the end of a game, but not much else. G

Amazing work! I should have visited this forum more often. Keep it up,

Hello again everyone - keep an eye out on this and other boards for some posts soon from beta testers - I'm delighted to announce that the end of my 20+ year quest to have my own playable vector-based tailgunner has arrived :-)
Thomas Sontowski - the designer of the VecFever cartridge and author of several Vectrex games - has extended the functionality of the VecFever so that it can run C code in the cartridge itself - no external Mac or Linux needed - and is currently beta-testing this new feature by using Tailgunner as a test case. He's also making a few (not for sale) standalone Tailgunner cartridges (using the same processor as the vecfever but without the multicart features) for friends and family, but regular VecFever owners will be able to get the updated VecFever software from him and will be able to play Tailgunner on the Vectrex as it was meant to be!
I'll leave it to unbiased reviewers to comment on how well Tailgunner runs as a pseudo-native Vectrex game - all I'll say is that Thomas' reputation as a perfectionist appears to be well-earned :-)
And to those of us here who are big tailgunner fans: this implementation *does* record your high score :-)

So it's C code cross-compiled to run on the CPU in the VecFever? Is the source MAME or a rewrite?
It looks excellent on the Malban YouTube video!

It looks excellent on the Malban YouTube video! the source is from scratch, with the CCPU to C translation being heavily based on earlier CCPU emulator and disassembler code from Zonn Moore, Neil Bradley and Jeff Mitchell. The same code did end up in MAME but this implementation didn't use any of MAME. G

Perfect, native 6809! I remember the discussion all those years about the zvg. It was like the VecFever, gone before anyone could get one :-) It case anyone's interested: www.zektor.com/zvg/index.htmlEDIT: turns out it isn't a native 6809 binary, it's running on the VecFever ARM CPU.
